Problem summary tanker general failure analysis and elimination
In terms of building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, and fibers, PVC was the world`s largest production of general-purpose plastics, and its applications are very widely. Widely used in all aspects
PVC is a white powder with an amorphous structure. The degree of branching is relatively small. The relative density is about 1.4. The glass transition temperature is 77~90°C. It begins to decompose at about 170°C. It has poor stability to light and heat. After prolonged exposure to sunlight, it will decompose to produce hydrogen chloride, and further automatically catalyze the decomposition, causing discoloration, and the physical and mechanical properties also rapidly decline. In actual applications, stabilizers must be added to improve the stability of heat and light.
The production process of PVC Resin SG8 and PVC RESIN SG5 is basically the same, and the production equipment is exactly the same. The main difference lies in the formulation of additives, polymerization temperature, reaction pressure and so on. The reaction temperature and reaction pressure of SG-8 resin have basically reached the working pressure limit of the polymerizer. The reaction requirements are relatively strict, and the requirements on operation, safety, technology, and personnel quality are more stringent, and the resin quality is more difficult to control.
